Description

Like other ciliates two types of nuclei are present. A germinative micronucleus and a RNA-producing macronucleus. Both have nuclear envelopes with pores and both have ribosomes attached to their outer membranes. Heterochromatin bodies are the only prominently stained entities in the micronucleus. A few microtubules are also present. TEM taken on 3/29/71 by R. Allen with Hitachi HU11A operating at 75kV. Mag. 13,750X. Bar = 0.5µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. There is a high resolution version of this image in the library (CIL:39452) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).

Technical Details

Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
